PTB Physikalisch-Technische Bundesanstalt

LISUN has many customers from Europe, and the instruments and service provided by us have passed the calibration and certification of PTB Physikalisch-Technische Bundesanstalt. Since 2003, LISUN has cooperated closely with German PTB through technical discussions and calibration transfer.

The Physikalisch-Technische Bundesanstalt (PTB) is the national metrology institute of the Federal Republic of Germany, with scientific and technical service tasks. It is a higher federal authority and a public-law institution directly under federal government control, without legal capacity, under the auspices of the Federal Ministry for Economic Affairs and Energy.

PTB is headed by the Presidential Board in Braunschweig, which is composed of the President, the Vice-President and a further member. Another executive committee is the Directors’ Conference, with the Presidential Board and the Heads of the Divisions as members. PTB is advised by the “Kuratorium” (PTB’s Advisory Board), which is composed of representatives from science, the economy and politics. PTB is composed of the following 9 Divisions:
•  Division 1: Mechanics and Acoustics (site: Braunschweig) with the following departments: Mass, Solid Mechanics, Velocity, Gas Flow, Liquid Flow, Sound, Acoustics and Dynamics
•  Division 2: Electricity (site: Braunschweig) with the following departments: Direct Current and Low Frequency, High Frequency and Electromagnetic Fields, Electrical Energy Measuring Techniques, Quantum Electronics, Semiconductor Physics and Magnetism, Quantum Electrical Metrology
•  Division 3: Chemical Physics and Explosion Protection (site: Braunschweig) with the following departments: Metrology in Chemistry, Analytics and Thermodynamic State Behavior of Gases, Thermophysical Quantities, Physical Chemistry, Explosion Protection in Energy Technology, Explosion Protection in Sensor Technology and Instrumentation, Fundamentals of Explosion Protection
•  Division 4: Optics (site: Braunschweig) with the following departments: Photometry and Applied Radiometry, Imaging and Wave Optics, Quantum Optics and Unit of Length, Time and Frequency
•  Division 5: Precision EngineerinꞋ (site: Braunschweig) with the following departments: Surface Metrology, Dimensional Nanometrology, Coordinate Metrology, Interferometry on Material Measures, Scientific Instrumentation Department
•  Division 6: Ionizing Radiation (site: Braunschweig) with the following departments: Radioactivity, Dosimetry for Radiation Therapy and Diagnostic Radiology, Radiation Protection Dosimetry, Ion and Neutron Radiation, Fundamentals of Dosimetry, Operational Radiation Protection
•  Division 7: Temperature and Synchrotron Radiation (site: Berlin-Charlottenburg and Adlershof) with the following departments: Radiometry with Synchrotron Radiation, Cryophysics and Spectrometry, Detector Radiometry and Radiation Thermometry, Temperature, Heat and Vacuum
•  Division 8: Medical Physics and Metrological Information Technology (site: Berlin-Charlottenburg) with the following departments: Medical Metrology, Biosignals, Biomedical Optics, Mathematical Modeling and Data Analysis, Metrological Information Technology
•  The Presidential Staff Office and the Press and Information Office as well as the Divisions Z (Administrative Services) and Q (Scientific-technical Cross-sectional Tasks) report directly to the Presidential Board. Division Q comprises, among other things, the Academic Library, the Legal Metrology and Technology Transfer Departments, the Technical Services, and the Technical Cooperation Department.
